SPECIFICATION forming part of Letters Patent No. 417,152, dated December10, 1889.

Application filed July 27, 1889, Serial No. 318,976. (No model.)

To all whom, it may concern:

Be it known that I, JAMEs A. CowLEs, a citizen of the United States,residing at ,(Jhicage, in the State of Illinois, have made certain newand useful Improvements in Hydrocarbon-Burners, of which the followingis a specification, reference being had to the accompanying drawings.

Figure 1. is a side elevation of my improvement. Fig. 2 is a plan view.Fig. 3 is an end View. Fig. 4C is an end view of one of the forkedbrackets used and two air-chambers in position, but removed from theflamespreader. Fig. 5 is a view in vertical section of two air-chambers.Fig. 6 is a side elevation of forked'braeket and lower air-chamher. Fig.7 is a detail of upper air-chamber and arm. Fig. 8 is a side elevationof burner located in a coolestove.

The object of this invention is to provide a serviceablehydrocarbon-burner, and the nature of its construction is herein shown.

A is a retort-pipe formed and coiled in parallel lines, as shown in Fig.-2, with one end at about the center of the coil bent downward, asindicated in the dotted lines in Fig. 1.

B is the flame-spreader, made of sufficient length and width, andangular in form, as particularly shown in Fig. 3, with the angularsurface on the under side, and within this angular-shaped flame-spreaderis located the retort-pipc A. From the center of the under side of theflame-spreader descends the tube C, and through this tube passes thevertical part of the retort-tube A. To the lower end of this verticalpart of the retort-pipe attached a common. T-conneetion, to which isattached the pipes E E at the right and left. These two pipes and the Tconstitute and form the burner-pipe. At or near each end of theburner-pipe is a jet-hole F.

G is an angular bracket having the upper end H forked, which forks fitsnugly against the outer angular surface of the flame spreader, and areattached thereto by screws or nuts and at the other end support theairchamber 1, which is located immediately over the jet-hole F.

J is a second air-chamber, located above the first one I, and supportedby an arm K extending therefrom and attached to bracket G by means of ascrew. This arm is angular,

so as to locate the air-chamber directly over the first one. (See Fig.7.) Belowthe burnerpipe is located the lighter-pan L.

The outer or supply end of retort-pipe A is connected with anycontinuous supply of oil, which 'oil is governed in its flow into theretort-pipe by valves in the usual way. At first a limited supply of oilis allowed to pass into the retort-pipe, when it soon appears In thelighter-pan L, in which is placed any kind of wickingpreferablyasbest-us. A lighted match is applied. In a short time the retortpipeand flame-spreader above are sufficiently heated to readily vaporize theoil as fast as it is fed into the pipe-retort, whence it passes downinto the burner-pipe and out through the jet-holes F F, (when it isigniteth) up through the two air-chambers I and J. These twoair-chambers serve the purpose of con centrating around and mingling airwith the upwardly and rapidly moving flame. This is done in eachchamber; hence twice as much air is mingled with the flame by the use oftwo chambers aswhen but one is used, and hence the more thorough andcomplete is the combustion. The upper air-chamber has a wlder opening atthe base than the lower one has, so.

that it can extend over the first one and leave a space between the twofor air to enter the second one. As the fiaine escapes from the upperchamber it impinges against the angular flame-spreader above, and by theangle is divided and passes a part to each side of the spreader. Theflame as it impinges against the oblique sides of the flame-spreadergives forth a milder and softer sound or noise than when it impingesagainst the surface of a flamespreader at right angles with the courseof the flame. This form of the flame-spreader renders the noise soft andunobjectionable. This flamc-sp reader also serves as a protector to theretort-pipe against the intense heat arising from the combustion.

The tube C protects the vertical part of the retort-pipe.

This burner can be used in cook or heating stoves, or in ordinarygrate-fires. The angular flame-spreader is in the form of a trough withthe bottom shaped as shown in Fig. 3.

I clain1 Y In a hydrocarbon-burner, the combination, 5 with a hollowangular flame-spreader, of a retort-pipe located Within the Spreader andterminating in a burner located beneath the I spreader, angularbracket-arms secured to i the spreader, and air-chambers supported by Isaid bracket, substantially as described.
